Book Synopsis Tailoring Ultrashort Pulses for Surface Structuring and Characterizing Ultrashort Pulses by : Billy Lam (Optics scientist)

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis is focused on the methods for tailoring ultrashort pulses for surface structuring and the methods for characterizing ultrashort pulses. In other words, the primary goal is to modulate as well as measure the spatio-temporal electric field E(x, y, t) = |E(x, y, t)|e i[phi](x,y,t) of an ultrashort pulse. Existing vector optical field (VOF) generators are either inefficient or require many optical elements with intensive alignment. I have demonstrated both a non-diffraction-based and a diffraction-based VOF-generator with a theoretical efficiency close to 100% using a spatial light modulator (SLM) to shape the focus of a femtosecond (fs) laser beam arbitrarily for surface structuring. Besides the beam focus, I have also fabricated curved laser-induced periodic surface structure (LIPSS) out-of-focus by controlling the polarization distribution of the beam. Both VOF-generators are compact with only a few optical elements and are easy to align for fs laser beams. These methods present an effective and energy-efficient way to shape the fs laser beam dynamically to create complex surface structures. For beam characterization, I have developed the wedged reversal shearing interferometer (WRSI), consisting of a single beam splitter cube (BSC), to retrieve the spatially resolved electric field E(x, y). The main advantages of the WRSI over existing techniques are its simplicity, stability, robustness, capability, and guaranteed zero-delay for ultrashort pulses. The WRSI can also be used together with a scanning Michelson interferometer, along with an additional temporal measurement using frequency-resolved optical gating (FROG), to measure the spatio-temporal field E(x, y, t). In addition, this thesis explores a new method to temporally characterize (E(t)) an ultrashort pulse with precise information on the carrier-envelope phase (CEP) in a single-shot operation. A feat unachievable by previous methods such as FROG and spectral phase interferometry for direct electric-field reconstruction (SPIDER), since spectrally resolved autocorrelation and spectral shear are insensitive to the CEP. The CEP is an important parameter of a few-cycle pulse because the CEP can vary from pulse to pulse and has a large impact on laser-matter interaction. The ability to measure the spectral phase and CEP of an arbitrary non-repeating ultrashort event is important for the study of ultrafast optical phenomena"--Pages xi-xii.

Book Synopsis Few-Cycle Laser Pulse Generation and Its Applications by : Franz X. Kärtner
Download or read book Few-Cycle Laser Pulse Generation and Its Applications written by Franz X. Kärtner and published by Springer Science & Business Media. This book was released on 2004-09-14 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the physics, technology and applications of short pulse laser sources that generate pulses with durations of only a few optical cycles. The basic design considerations for the different systems such as lasers, parametric amplifiers and external compression techniques which have emerged over the last decade are discussed to give researchers and graduate students a thorough introduction to this field. The existence of these sources has opened many new fields of research that were not possible before. These are UV and EUV generation from table-top systems using high-harmonic generation, frequency metrology enabling optical frequency counting, high-resolution optical coherence tomography, strong-field ultrafast solid-state processes and ultrafast spectroscopy, to mention only a few. Many new applications will follow. The book attempts to give a comprehensive, while not excessive, introduction to this exciting new field that serves both experienced researchers and graduate students entering the field. The first half of the book covers the current physical principles, processes and design guidelines to generate pulses in the optical range comprising only a few cycles of light. Such as the generation of relatively low energy pulses at high repetition rates directly from the laser, parametric generation of medium energy pulses and high-energy pulses at low repetition rates using external compression in hollow fibers. The applications cover the revolution in frequency metrology and high-resolution laser spectroscopy to electric field synthesis in the optical range as well as the emerging field of high-harmonic generation and attosecond science, high-resolution optical imaging and novel ultrafast dynamics in semiconductors. These fields benefit from the strong electric fields accompanying these pulses in solids and gases during events comprising only a few cycles of light.

Download or read book A New Generation of High-Power, Waveform Controlled, Few-Cycle Light Sources written by Marcus Seidel and published by Springer. This book was released on 2019-02-01 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents first successful experiments to carrier-envelope-phase stabilize a high-power mode-locked thin-disk oscillator and to compress the pulses emitted from this laser to durations of only a few-optical cycles. Moreover, the monograph introduces several methods to achieve power-scalability of compression and stabilization techniques. All experimental approaches are compared in detail and may serve as a guideline for developing high-power waveform controlled, few-cycle light sources which offer tremendous potential to exploit extreme nonlinear optical effects at unprecedentedly high repetition rates and to establish table-top infrared light sources with a unique combination of brilliance and bandwidth. As an example, the realization of a multi-Watt, multi-octave spanning, mid-infrared femtosecond source is described. The thesis starts with a basic introduction to the field of ultrafast laser oscillators. It subsequently presents additional details of previously published research results and establishes a connection between them. It therefore addresses both newcomers to, and experts in the field of high-power ultrafast laser development.

Book Synopsis Measuring the Spatiotemporal Electric by : Pamela Bowlan
Download or read book Measuring the Spatiotemporal Electric written by Pamela Bowlan and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis a powerful and practical method for characterizing ultrashort pulses in space and time is described (called SEA TADPOLE). First we focus on measuring pulses that are spatially uniform but very complicated in time or frequency. We demonstrate and verify that SEA TADPOLE can measure temporal features as small as 30 femtoseconds over durations as long as 14 picoseconds. The spectral resolution of this device is carefully studied and we demonstrate that for certain pulses, we achieve spectral super resolution. We also develop and test an algorithm for measuring polarization shaped pulses with SEA TADPOLE. Our simple interferometer can even be used to measure the spatiotemporal electric field of ultrashort pulses at a focus. This is because SEA TADPOLE samples the field with an optical fiber which has a small core size. Therefore this fiber can be used to spatially sample the beam, so that the temporal electric field can be measured at every position to obtain E(x, y, z, t). The single mode fiber can be replaced with an NSOM (Near Field Scanning Optical Microscopy) fiber so that spatial resolution as low as 500nm (and possibly lower) can be achieved. Using this device we make the first direct measurements of the compete field of focusing ultrashort pulses. These measurement can be viewed as "snap shots" in flight of the focusing pulse. Also, for the first time, we have observed some of the interesting distortions that have been predicted for focusing ultrashort pulses such as the "forerunner" pulse, radially varying group delay dispersion, and the Bessel-like X-shaped pulse. We have also made the first direct measurements of the electric field of Bessel X-pulses and their propagation invariance is demonstrated. We also use SEA TADPOLE to study the "boundary wave pulses" which are due to diffraction.
Book Synopsis Thin Film Micro-Optics by : Ruediger Grunwald
Download or read book Thin Film Micro-Optics written by Ruediger Grunwald and published by Elsevier. This book was released on 2007-02-19 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Thin-film microoptics" stands for novel types of microoptical components and systems which combine the well-known features of miniaturized optical elements with the specific advantages of thin optical layers. This approach enables for innovative solutions in shaping light fields in spatial, temporal and spectral domain. Low-dispersion and small-angle systems for tailoring and diagnosing laser pulses under extreme conditions as well as VUV-capable microoptics can be realized. Continuous-relief microstructures of refractive, reflective and hybrid characteristics are obtained by vapor deposition technologies with shadow masks in rotating systems. The book gives a comprehensive overview on fundamental laws of microoptics, types of thin-film microoptical components, methods and constraints of their design, fabrication and characterization, structure transfer into substrates, optical functions and applications. Recent theoretical and experimental results of basic and applied research are addressed. Particular emphasis will be laid on the generation of localized, nondiffracting few-cycle wavepackets of extended depth of focus and high tolerance against distortions. It is shown that the spectral interference of ultrabroadband conical beams results in spatio-temporal structures of characteristic X-shape, so-called X-waves, which are interesting for robust optical communication. New prospects are opened by exploiting small conical angles from nanolayer microoptics and self-apodized truncation of Bessel beams leading to the formation of single-maximum nondiffracting beams or "needle beams". Thin-film microoptical beam shapers have an enormous potential for future applications like the two-dimensional ultrafast optical processing, multichannel laser-matter interaction, nonlinear spectroscopy or advanced measuring techniques. - Introduces a new and promising branch of microoptics - Gives a compact overview on the types, properties and applications of the most important microoptical components containing valuable data and facts- Helps to understand the basic optical laws - Reports on the historical development line of thin-film microoptics - Provides brand new results of research and development in the field of ultrashort-pulse laser beam shaping and diagnostics- Discusses the future trends and first approaches of next generation microoptics- Contains a carefully assorted glossary of the most important technical terms

Book Synopsis Measuring the Electric Field of Picosecond to Nanosecond Pulses with High Spectral Resolution and High Temporal Resolution by : Jacob Arthur Cohen
Download or read book Measuring the Electric Field of Picosecond to Nanosecond Pulses with High Spectral Resolution and High Temporal Resolution written by Jacob Arthur Cohen and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We demonstrate four experimentally simple methods for measuring very complex ultrashort light pulses. Although each method is comprised of only a few optical elements, they permit the measurement of extremely complex pulses with time-bandwidth products greater than 65,000. First, we demonstrate an extremely simple frequency-resolved-optical gating (GRENOUILLE) device for measuring the intensity and phase of pulses up to ~20ps in length. In order to achieve the required high spectral resolution and large temporal range, it uses a few-cm-thick second harmonic-generation crystal in the shape of a pentagon. This has the additional advantage of reducing the device's total number of components to three. Secondly, we introduce a variation of spectral interferometry (SI) using a virtually imaged phased array and grating spectrometer for measuring long complex ultrashort pulses up to 80 ps in length. Next, we introduce a SI technique for measuring the complete intensity and phase of relatively long and very complex ultrashort pulses. It involves making multiple measurements using SI (in its SEA TADPOLE variation) at numerous delays, measuring many temporal pulselets within the pulse, and concatenating the resulting pulselets. Its spectral resolution is the inverse delay range--many times higher than that of the spectrometer used. The waveforms were measured with ~ fs temporal resolution over a temporal range of ~ns and had time-bandwidth products exceeding 65,000, which to our knowledge is the largest time-bandwidth product ever measured with ~fs temporal resolution. Finally, we demonstrate a single-shot measurement technique that temporally interleaves hundreds of measurements with ~fs temporal resolution. It is another variation of SI for measuring the complete intensity and phase of relatively long and complex ultrashort pulses in a single shot. It uses a grating to introduce a transverse time delay into a reference pulse which gates the unknown pulse by interfering it at the image plane of an imaging spectrometer. It provided ~125 fs temporal resolution and a temporal range of 70 ps using a low-resolution spectrometer.

This book was released on 2006-06-15 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.
